This study aims to assess the spatial and temporal variations of aerosol pollutants within the nine selected ambient air monitoring stations, including residential, commercial, and industrial sites in Paradip city based on two seasons, i.e., winter and summer, from January 2019 to June 2019. The particulate matter (PM) like PM10 and PM2.5 and gaseous pollutants like sulphur dioxide (SO2), nitrogen dioxide (NO2), and ammonia (NH3) samples were collected at each monitoring stations. The 24-hour average concentrations of PM10 and PM2.5 showed the highest levels in the winter season and lowest in the summer season. The value exceeded the permissible limit of India-national ambient air quality standards (IND-NAAQS) at all the monitoring stations.
